Twin Turbo 1971 Scamp Project
This exercise was meant to show that you don't HAVE to have a 4-valve head and a Japanese engine to go pretty fast in an A-body. All it takes is a well-tuned /6 and a hairdryer...
Not as exotic nor as fast as the twin-turbo Supra deal, but an easier car to put together, and sometimes that's a significant advantage. Just sayin'....
As a guy who SUPPORTS a propane injected turbo slant I know the engine's great potential with boost. I also know its weaknesses, (4 main bearings, head sealing, overdrive automatics, etc.) There is no comparison of these two engines as the 2JZ has had 30 years of technology to draw from. I guarantee that your car will still be faster 1 year from now because we set our objectives on upgrades that did not reduce the engine's reliability or super quiet 550 rpm idle.
The 2JZ is simply amazing to drive and as I have driven both setups. I can only say that having a Scamp with modern features like EFI, Variable Valve Timing, and Sequential Turbocharging is just outside anyone's expectations and the midrange and upper RPM power is intoxicating even at the stockish boost levels. The car is not fast yet as we are still making it a "CAR", fixing wheel alignments, pinion angles, small leaks, etc. Remember this was a non-op neglected car that needed everything!
If someone wants a "KIT", we would certainly help with that. Personally I'd rather see a really nice EFI and Turbo setup for the Slants and I would be happy to invest the cash and engineering time for this IF we get some serious interest in "KITS" BEFORE you will see us, (Timmy and me), make a 2JZ install kit. I'd like to do a 12 PSI intercooled EFI, (Megasquirt based), kit where we'd provide the headers, intake, intercooler, etc. Be real cool to see some 330 RWHP Slants killing Chevelles on the streets! I don't like the Slant cylinder head and I will say that forever but unless 150-200 of us want to spend a grand on crowd sourced head tooling and production we are stuck with a non cross flow iron head.
I am keeping NO SECRETS with our Supra swap as I would be honored to help someone do just what we did. The first one is always expensive as it's all, "Will this work?"
Bill, as always you've done well and I admire your professional outcomes with your cars. I hope we can meet up sometime as I want you to drive the Scamp!
